CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/209069
Kind Code:
A1
Abstract:
According to the present invention, this particulate matter detection sensor has an element part (200) that is a part for detecting a particulate matter and a heat generation unit (211) that is a part configured as an electric heater for heating the element part. A control device (20) of the particulate matter detection sensor comprises: a temperature acquisition unit (12) for acquiring the temperature of the element part; a heat generation adjustment unit (13) for adjusting the heat generation amount of the heat generation unit on the basis of the temperature of the element part acquired by the temperature acquisition unit; and a storage unit (14) for storing a correspondence relationship between the value of electric power consumed in the heat generation unit and the temperature of the element part. The temperature acquisition unit is configured to acquire the temperature of the element part on the basis of the value of the electric power consumed in the heat generation unit and the correspondence relationship.
